ELISHA WATERS, OF TROY, NEW YORK.

TOOL-HOLDER.

SPECIFICATION forming part of Letters Patent No. 338,322, dated March 23, 1886,

Application filed June 16, 1885.

T0 aZZ whom it may concern;

Be it known that I, ELISHA Runes, of Troy, in the county of Rensselaer and State of New York, have invented certain Improvements in Tool-Holders, of which the following is a specification.

This invention relates to a device for holding edge-tools and presenting the same in the required position to the surface of a grindstone or other abrading-surface; and it con sists, essentially, in a jointed frame provided at opposite ends with a supporting-roll and a tool-holding clamp, its two parts being connected by an adjustable rod, so that the angle of the tool with reference to the grinding-surface may be varied at will.

Referring to the drawings, Figure 1 represents a perspective View of my holder. Fig. 2 is a side elevation 'of the same as it appears when in action.

Referring to the drawings, the two plates A and B,jointed together at one end, constitute the body of the holder. The plate A is provided at one end with asupporting-roll, O, the journal or pivot of which is mounted in cars depending from the edges of the plate. The plate B, the upper surface of which is adapted to give support to plane-bodies, chisels, and other edged tools, is provided with an overlying bar or stirrup, D, having at the middle a set-screw, E, by which the tool may be confined firmly in position thereon. The two parts of the frame are further connected by a rod, F, one end of which is pivoted to ears on the under side of the plate B, while the opposite end is extended through a swivcling bar, G, or equivalent guide on the under side of the plate A. A spiral spring, H, surrounding the rod tends to bring the parts A and B to a common plane, or in line with each other, while a nut, I, applied to the threaded end of the rod serves as a means of throwing the two parts A and B out of line, so as to cause the edge of the tool carried by the part B. to be presented at a greater or less angle to the grinding-surface.

In making use of the device, the blade or Sen-in "0.1681344. (No n1odel.l

tool is inserted beneath the stirrupD and confined in place by the screw E, its edge projecting beyond the plate B. The device is thus placed in position upon the grindingsurface, as shown in Fig. 2, one end being sustained and carried by the roller 0, while the opposite end is sustained by the tool, the edge of which is permitted to bear upon the grinding surface, as plainly represented in Fig. 2.

The device forms a light, simple, and convenient means by which the attendant may present the tool steadily and firmly to the grindingsurface at any angle required.

Having thus described my invention, whal I claim is 1. The tool-holder consisting of thejoint-ec' frame provided with the supporting-roll anc a toolclamping device at opposite ends, anC with means, substantially as described, forad justing the angle of thejointed parts with re spect to each other.

2. The plate A, having a supporting-ro1l,0 in combination with the plate B, jointed there to, and provided with the bar D and screu E, the rod F, spring H, and nut l'.

3. In a tool-holder, a transverselyjointet frame provided with a supporting-roll and 2 tool-clamp at opposite ends, in combinatioi with a screw for bending or flexing the frame and a spring tending to straighten the semi as it is relieved from the action of the screw 4. In a tool holder, the plate A, provide( with the roller 0 and swiveled bar G, in com bination wi.h the plate B,jointed thereto an provided with the tool-clamping device, th rod F, jointed to the part B and extende through bar G, the spring H, applied to th inner end of said rod, and the nut I, applier to the outer end of the same.

In testimony whereof I hereunto set my ham in the presence of two attesting witnesses,

ELISHA WATERS.
